TeraFlex Alpine RT (Rogue Trail) Suspension Systems build on our already capable Alpine CT (Cross-Trail) Suspension Systems. These systems include all our top-of-the-line components. The 2.5 inch Alpine RT2 Short Arm Suspension System features Alpine IR Short Control Arms with our all-new IR (Independent Rotation) Bushings.
These adjustable control arms and bushings team up to give your rig an unprecedented smooth and quiet ride both on- and off-road. Additionally, the included SpeedBump Front Bump Stops take the hard hits out of those unexpected trail surprises.
Our adjustable Alpine IR Short Control Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 0-4.5 inch lifts. The adjustable Alpine IR Front Track Bar and Front (3.5 inch and up) and Rear Track Bar Brackets improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling.
In addition to optimizing suspension geometry, our long and short adjustable Alpine IR Control Arms feature our all-new IR (Independent Rotation) Bushings. These innovative bushings remove bushing bind during full suspension travel whether on the highway or the trail. This results in unrestricted droop as well as a noticeable ride improvement.
This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat.
IR Bushings reduce bind during droop for less overall bushing load during articulation. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH). Alpine RT Suspension Systems are for the Jeeper who wants it all!
Does not include shocks. We recommend Falcon Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. Alpine RT Suspension Systems are offered with select Falcon SP2 Mode Adjust Piggyback Shocks including: 3.5 aDAPT e-Adjust, 3.3 Fast Adjust, or without shock absorbers. Other Falcon shocks are available separately.
